CULINARY VESSEL.

SPECIFICATION forming part of Letters Patent No. 260,4'70, dated July 4,1882.

Application filed May 2, 1882. (No model.)

To all whom it may concern:

Be it known that I, JOHN W. FISHER, a citizen of the United States,residing at N ewYork, in the county of New York and State of New York,have invented certain new and useful Improvements in Culinary Vessels;and Ido declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to that class of culinary utensilsin which avessel of earthenware or other suitable material is inclosed in ametallic casin g or shield, thereby forming a space or air-chamber fortheaccumulation and constant circulation of heat in contact with theentire outer surface of the vessel.

The invention consists, first, in the combination,with such culinaryvessels, of a strengthening-frame adapted to support and hold the crocktogether in the event of its becoming fractured while in use 5 and,second, in the means of connecting the vessel and its inclosing band orjacket, as hereinafter more fully set forth.

In the annexed drawings, illustrating the invention, Figure l is a sideelevation of a kettle embodying my invention. Fig. 2 is a verticalsection of the same. Fig. 3 is a bottom view. Fig. 4 representsaniodificatiou in the construction of the supporting-frame. Fig. 5 is apartial side view and section of the upper portion of the vessel,showing one manner of connecting the crock and its inclosing shield.Fig.6 represents several sectional details, illustrating variations inthe form of the annular shoulders with which the exterior of the crockis provided; and Fig. 7 is ahorizontal section through the uppercorrugated portion of the band or shield and the inclosed crock.

Like letters of reference are used to designate the same parts in theseveral views. I

The inner vessel, bowl, or crock, A, may be made of earthenware or othersuitable material and in any desired form, its sides being preferablytapered from above downward, as shown in Fig. 2.

On the outer surface of the vessel A, near its upper part,is*formedeither one or more annular shoulders, a a, for the attachment of theinclosiug band or shield B and the intermediing employed either with orwithout an annular groove, 1), as may be desired. The inclosing band orshield B is composed of Russia iron or other suitable metal, and ispreferably corrugated at its upper edge, as shown in Figs. 1 and 7, thusholding the crock or vessel A with an elastic grip that is readilyadapted to varying sizes of crocks.

If desired, the crock may be formed with an annular series ofdepressions, c, intowhich the upper part of the band B may be pressed,as shown in Fig. 5,a firm connection of the parts being thus secured.The band B may also be bent so asto form aninternal annular projection,d,for engagement with the annular shoulder, as illustrated in one of thedetails shown in Fig. 6. The outer face of the crock above the shouldersmay be either vertical or inclined, as preferred. Before securing thecrock or vessel A within the band B the auxiliary supporting orstrengthening frame 0 is placed in position, as shownin Fig. 2. Thisframe maybe composed of sheet metal, as shown in Fig. 3, or of wire, asshown in Fig. 4., and consists of arms 0, attached to a ring orperforated disk, 0, the arms being arranged to grasp the sides of thevessel while the disk or ring is placed in contact with its bottom. Thisframe serves to support and strengthen the creek, and will holdit sothat in case of its breakage while in use the parts will not separate orfallto pieces.

The vessel is provided with a bail and a cover of any suitableconstruction.

It will he observed that the crock or vessel A is so arranged that anair-space is formed between it and the inclosiug band B, a space beingalso left beneath the crock by reason of its not extending quite to thebottom of the inclosiug band or shield. In this space or chamber theheat thatrises from the stove has ample opportunity to circulate incontact with the sides and bottom of the vessel, being thus atestrengthening-frame, 0, said shoulders beuniformly applied and obviatingany liability of scorching the contents of the vessel. It is obviousthat this principle may be utilized in the construction of tea andcoffee pots, saucepans, and other culinary vessels, whether large orsmall.

The advantages of arranging an earthenware vessel within a metallicsupporting-band will be apparent when such vessels are used for cooking,the development of deleterious acids being thereby prevented withoutinvolving the expense of an enameled metallic vessel, and without anysacrifice of strength and durability. It will be seen that by means ofthe corrugations formed in the upper portion of the band or shield B itis securely attached to the vessel or crock in such a manner as to bereadily removed when required. These corrugations also enable the bandto be readily applied to varying sizes of crooks without involving-thenecessity of any special fitting.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with an earthenware vessel, of a metallic inclosin gband having an upper corrugated edge adapted to grasp the vessel,thereby supporting the same, substantially as described.

2. The combination of the vessel A, having one or more annularshoulders, at, the inclosing band B, secured thereto, and anintermediate supporting or strengtheningframe composed of the arms 0 anddisk or ring 0, substantially as and for the purpose described.

3. The combination, with the vessel A, having an annular series ofdepressions, c, of the inclosing band B, having its upper portionpressed into engagement with said depressions, substantially as shownand described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN \V. FISHER.
